POP3 stops working

[Baga]

Somebody!
I am sick of it... half a year ago all of a sudden my Outlook stopped
working with POP3 accounts. I did some reading. Microsoft people of
cause blaimed anitviruses, firewalls, adviced to install SP2 for XP and
such. Nothing of that applied to me - i have SP2, no active antivirus
(do scan 1/week), no firewall (i think NAT router is enough of a
protection). When this same thing happened to SECOND machine (in a day
or two), i started suspecting windows updates. And sure enough - after
some binary searching i found that it was one of the updates!
Unfortunately i lost the number, it was something KB9811..., maybe
something else.

So, i uninstalled the update on both of the machines and marked it
"don't install" on microsoft update site. Silly me, i thought it's
over... Either that setting (not to install update) broke, or the
update was included into some later cumulative pack, but it is back
again - POP3 it completely broken!

Here is screenshot of Outlook errors reported:

I did try different clients and yes, everything is fine with servers
(all my POP3 account stopped working at the same time). I don't want to
spend a day sifting through windows updates to find which one did it to
me! Please, if somebody found that already, reply...

Cannot say that I've experienced any problems with critical winupdates and
OL, on a number of PC's

Well, lucky you...
So far at least one of two my machines is still functional (POP3, that
is)
Anybody saw / heard of / fixed problems like mine?
I hate to start uninstalling updates again...

I wasnt meaning anything by the comment.
Anything shown in Event Logs?

Thanks for advice!
Nothing in the Applications log regarding Outlook though...
However, it is flooded with such errors:

Event Type: Error
Event Source: vmauthd
Event Category: None
Event ID: 100
Date: 8/12/2006
Time: 1:05:45 PM

Description:
Cannot find perfmon object in array returned by perfDLL, index=0

I don't know if it is related at all. These errors appear at times
unrelated to Outlook startup or failed attempts to connect.

Also, here is another error from System log:

Event Type: Warning

App log:
That would appear to be an error relating to Vmware.

Re sys err, maybe
http://support.microsoft.com/kb/328948/ ,I know it refers to win2k
There are also reports of a lsasrv.dll virus, or at least virus that
replaces this sys file.

OK, thanks for the explanation. I'll keep an eye on those errors.

Looks like i was right and they have nothing to do with Outlook problem
- namely POP3 completely non-functional.
